Brain VR is a model of the human brain viewable in virtual reality using Google Cardboard. The model is derived from a typical human brain that was digitized in the 1970's at UC San Diego's School of Medicine.

You can look at a brain structure and press a button on the controller to have the app speak the name of the structure.
Works great with Chromecast, use it to give a tour of neural anatomy to a class!
